Transitions of CH₃OH, v_t = 0 covered by our ALMA survey. The best-fit LTE synthetic spectrum of CH₃OH, v_t = 0 is displayed in red and overlaid on the observed spectrum of Sgr B2(N1S), shown in black. The blue synthetic spectrum contains the contributions from all molecules identified in our survey so far, including from the species shown in red. The central frequency and width are indicated in MHz below each panel. The angular resolution (HPBW) is also indicated. The y-axis is labeled in brightness temperature units (K). The dotted line indicates the 3σ noise level.
